Been using this for a long time now and this is one of the best brands not just for price but TRUE QUALITY. I am a runner and cyclist and have noticed a change in my VO2 Max. It really helps the lungs not only for recovery but for when you are working at 80-95%

I personally never found any other more effective and active as this cordyceps. I tried many companies, but this is the best, I will only take off one star, because as I bought this supplement several times at IHerb, the capsules were broken, about 30 % of capsules were broken and cordyceps powder spread all over in the bottle, but I melted small amounts of this powder in water. I am of very good opinion about this particular cordyceps, as I use it for about 7 years, it was long time before I got to know IHerb shop, my friends were bringing it to me from the USA, now I am lucky to have this supplement at IHerb.
This product helped my mother to regulate blood pressure and it is the best supplement in any flu situation, it works against virus.

It seems to be more effective than the other Cordyceps which I've used in the past. Cordyceps increases peripheral blood flow, energy and strengthens the immune system. The capsules in the bottle I purchased was intact (unlike in cases I read about in other reviews. Apparently this problem has been fixed).
